SPECFICATION forming part of Letters Patent No. 742,965, dated-November 3, 1903.

Application filed August 25, 1902. Serial No. 120,896. (No model.)

To all whom, t Wta/ I/ concern:

Be it known that we, HENRY E. BRUNNER and EDIE J. PATTERSON, citizens ofthe United States, and residents of Haywards, county of Alameda, State of California, have invented certain new and useful Improvements in Hydrocarbon-Burners; and We do hereby declare the following to be a full, clear, and exact description of the same.

The present invention is designed more particularly for the utilization of crude or heavy oils, although equally as well adapted for the use of light oil, the object of the invention being to so construct the burner that the oil will be thoroughly commingled with the inflowing jet of steam and the` particles of the oil broken as conveyed through the burner toward its discharge-nozzle. By thus breaking up the oil, so to speak, the heavier particles contained therein are prevented from settling within the burner and from clogging or fouling the outlet-orifice of the nozzle-jet, While at the same time perfect atomization of the oil and steam is effected, resulting in a thorough commingling of the oil and steam. Perfect combustion and economy as to oil are obtained, inasmuch as the oil is prevented from settling Within the burner and running to waste.

To comprehend the invention, reference should be had to the accompanying sheet of drawings, wherein- `Figure l is a longitudinal sectional View of the oil-burner for the utilization of crudeor heavy oils, and Fig. 2 is a similar View of the burner adapted for the use of light oils.

The construction or design of the burner for heavy or crude oils only differs from that preferred for light oils in so far as relates to the nozzle attached thereto, although,if desired, either form illustrated in the drawings may be used for light oils or for heavy oils.

The form illustrated in Fig. l of the draw` ings is the construction of nozzle we prefer to utilize for heavy oils, as it is believed to insure absolute breaking of all particles contained in the oil. However, perfect combustion and breaking up of the particles of heavy oil has been successfully accomplished by the form of burner set forth in Fig. 2 of the drawings.`

In the drawings the burner-shell is indicated as being composed of sections l 2, to which the nozzle 3 is attached. The burnersections are formedwith a series of annular spray-riffies 4 5 6, against which impinges the body of oil and steam forced through the burner. These spray rifes or shoulders serve to break up the particles of oil carried by the jet of steam, so as to cause a thorough commingling of the steam and atomization of the oil carried in suspension by the impelled jet of steam. Through standing-glands 7 at outer end of burner-section l extends the steamnozzle 8, from which steam is ejected into the burner. 'To this nozzle 8 is connected by coupling 9 the steam-pipe l0, which supplies steam under pressure unto the steam-nozzle 8. The admission of steam to nozzle 8 is controlled or regulated by valve 11.

To the burner-section l is attached oil-supply pipe 12, through which oil is conveyed to the burner. The supply of oil through this oil-feed pipe is controlled by valve 13. The lower or discharge end ofthe oil-feed pipe is contracted in order to give a reduced outlet 14 to the oil. This contracted or throttled oil- Afeed outlet may be obtained in any suitable manner. We have found that a simple and efficient manner of so reducing the feed-outlet is to secure in lthe outlet end of the oilfeed pipe two oppositely-inelined plates 12 13a, the former being slightly greater in length than the latter, so that its terminal edge 14 extends to approximately the axial line of the outlet-orifice of the steam-nozzle 8. Over the extension or lip portion 14:a of plate l2a the oil escaped from outlet-opening 14 runs, flowing thereover by gravity until the lower or terminal edge 14:is reached. At this point the oil is picked up by the inflowing jet of steam and propelled to the jet or nozzle tip 16, attached to nozzle-section 3. As impelled through the burner the body of steam and oil impinges or strikes against the first annular rifle or shoulder 4 with sufficient force to scatter or break the flowing stream, after whichit again impinges against or strikes the annular riie or shoulder 5, where the breaking operation is repeated, which operation also takes place when annular shoulder Gis reached. Any number of annular riftles or shoulders may be employed to finterrupt the flow of the commingled IOO steam and oil toward the burner-nozzle 3; but it is believed two or three will suffice to thoroughly break up and atomize the oil.y

While the outer section 3 is designated as a nozzle, it may constitute a portion of burner proper, which may or may not be formed in sections.

In the case of heavy or crude oil being used we prefer that the outer or nozzle section be curved, as illustrated, and that a deilecting shield or diaphragm 18 be secured therein. Against this shield or diaphragm the propelled body of steam and oil strikes and is deflected downward into line with a second jet of steam ejected therein from steam-nozzle 19, which nozzle is attached to steam-pipe 10 by coupling 20. The flow of steam through nozzle 19 is controlled by regulating-valve 21. As the deflected stream is brought into line with the second steam-jet it is forced toward and out of outlet-orifice 22 of nozzle-tip 16. During its travel toward said outlet-orifice 22 the body of commingled steam and oil strikes against the annular riftle or shoulder 23. illustrated in Fig. l of the drawings a second annular riffle or shoulder 23' is provided. The object of said annular shoulders or riffles is to insure the breaking up of any particles of the heavy oil that may be held in suspension. By means of the inclined walls 24 of the nozzle-tip 16 the flowing body is directed to the outlet-orifice 22 in a thin stream.

Where light oil is used for the burner, 'a straight nozzle 25 may be utilized. In this case the second or auxiliary steam-jet may be dispensed with, although we prefer to form therein a single annular riille or shoulder 26 immediately in advance of the outlet-orifice of the nozzle-tip. By means of this rifile or shoulder the stream is broken up just prior to its discharge from the burner-tip.

While we preferably employ annular riffles or shoulders for breaking up the flowing stream, it is obvious that any shape of riffles may be employed that will answer the purpose.

Should any oil settle by gravity between the riffles, it will be picked up by the flowing stream as it rides over t-he rifile in advance thereof, and thus be again carried forward by the propelling-jet.

It will be understood that air under pressure may be admitted to the burner-shell in place of steam.

The essential feature of the invention consists in permitting the oil to fall onto the flowing jet of steam or air and subjecting the intermixed stream to the breaking action of a series of rifles interposed within the burner In the form of nozzleV intermediate the feed of the oil and the discharge-orifice of the nozzle-tip.

Having thus described our invention, what we claim as new, and desire to secure protection in by Letters Patent, is

1. `A burner of the character described comprising a plurality of sections assembled end to end and interlocked to form a continuous shell, the outer end of each section having an annular flange curved inwardly, the surface of -said flanges facing the inlet end of the shell being concaved so as to present abrupt obstructions in the line of feed therethrough whereby the spray may be broken and thrown backwardly, inlet-pipes at one end of the shell, and a discharge-nozzle at the opposite end thereof.

2. A burner comprising a shell, a downwardly-curved nozzle attached thereto, a depending shield or diaphragm arranged within the curved nozzle, a steam-nozzle extending into the burner-shell, an oil-feed pipe attached to the shell, a contracted outlet for the oil-feed pipe arranged to deliver oil into a flowing body of steam ejected into the shell from the steam-nozzle, a series of riffles interposed within the shell intermediate the oil-feed and the diaphragm of the curved nozzle, an auxiliary steam-nozzle extending into the nozzle, an outlet-tip secured to the nozzle, a riflle located within the nozzle between the diaphragm and nozzle-tip, and means for supplying steam to the steam-nozzles.

3. A burner of the character described having a single discharge-nozzle, said nozzle being offset, an oil-inlet pipe and a steam-inlet pipe aty the inner end of the burner, and an auxiliary' steam-inlet pipe arranged to discharge into said odset discharge-nozzle.

4. A burner of the character described having an oil-inlet pipe and a steam-inlet pipe oppositely-inclined deilectors carried by the oil-inlet pipe, the free ends of the deflectors approaching to form a passage therebetween, one of said delectors being relatively long IOS and projecting into the path of steam ejected v IIO
